Improvement in devices for drawing beer



. UNITED STATES THOMAS J. BYRNEpOF ERIE, PEENSYLV-ANIA, ASSIGNOR OF ONE-HALF RIGHT TO CLARK M. COLE, OF SAME PLACE.

PATENT orrrcn Specification forming part of Letters Patent No. 172,085, dated January 11, 1876; application filed November 2, 1875.

-My invention relates to improvements in that class of devices employed for forcing air into barrels, kegs,vand other similar vessels in order to produce sufficient pressure within the same to cause liquid contained therein to flow readily therefrom when the spigot or tap is open, the nature of which will be hereinafter fully explained by reference to the drawings, in which Figure 1 represents a horizontal section of an ice-box, with a barrel or keg contained therein, with my invention applied thereto. Fig. 2 represents a sectional view of the airpump. Fig. 3 showsa vertical section of the plug, and parts connected therewith. shows a detached view of parts.

In each of theviews similar letters of reference are employed to indicate corresponding parts wherever they occur.

L represents an ice-box, within which is supported a keg or barrel, A, provided with a spigot or tap, B, passing through to the exterior of the ice-box. G is an air-pump,-pro- Vided with'a cylinder, 0, and cap g, through which passes the rod H, on the end of which is mounted the plunger I, to the forward face of which is, by means of a peg or screw, it, connected a valve, K, provided with openings 70, and having a dishedrim, K, extending forward from the same. Within the rim K of the valve K is arranged a coiled spring, m, adapted at all times to keep the rim K firmly fitting against the inner periphery of the cylinder G. The extreme end of the cylinder G is fitted with a pipe or tube, a, to which is attached a flexible tube, F, the opposite manner that the end of the tube a shall be aboutlevel with the forward face of the notched projection E of the clamp E, and be capable of receiving an elastic washer or packing, 01 as shown by Figs. 3 and 4. D represents a valve, provided with a hollow stem, d, having a screw-thread, 01 formed on its periphery, adapted to be received and held in an opening formed in a plug, 0, adapted to be inserted in the upper side of the barrel or keg A, or into an opening in an enlargement, G, in the spigot B, as shown by Fig. 1. The front end of the valve D isprovided with a flat plate, D having parallel sidesD and rounded ends D", the diameter of which from D to D being such as just to pass between the ends of the projections E, and its length such that when the clamp E is placed overit and turned around, as shown by Fig. 3, the rounded ends D shall be received and held securely within the recesse's E of the clamp E, thereby holding the end of the pipe at (on which is arranged the washer or packing n within the conical end d in such manner that the washer a shall form a tight joint between the valve D and the pipe at. The end at of the hollow tube at is turned .down and provided with an external cylindrical valve, 19, adapted to cover a series of openings, 1), in such manner as to prevent the egress of air from the barrel through the hollow tube d, but to allow of its readily being forced through the openings 11 into the barrel or keg from the air-pump G. I

The operation of the apparatus is so well known, and, in view of the state of the art at the present-time, it is unnecessary to describe the operation of the same.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- l. The combination, with the valve D, having a hollow screwed stem, (1, plate D conical opening (Z passages p, and external 0y.- lindrical valve 11, of the clamp E, tube a, and

washer n substantially as shown and described. I j
